Former child actor Akanishi Ryou appears in "Female Body Dissection," where every nook and cranny of her body is measured! She appears in a twin-tailed bloomer outfit, and we suddenly take her temperature down there and in her ass! Excited by this sudden event, her temperature rises rapidly! When we make flat-chested gal Yuzuna get on all fours to test her vaginal pressure, "beep beep beep beep beep beep beep!!" Her vaginal pressure reaches its maximum the moment we insert our penis! We have to investigate this further...! And so we thrust in our cock injection!
